Abstract

The utility model relates to an air chamber type safety helmet which is formed by the combination of a helmet shell, a shockproof pad and an air chamber with an aerated air faucet, wherein the air chamber is additionally arranged between the helmet shell and the shockproof pad. The helmet of the utility model not only can efficiently prevent a wearer from suffering the harm of secondary impact caused by the looseness of the helmet, but also can relieve the stuffiness caused by the sealed helmet, and is widely suitable for various outdoor workers and motorcycle drivers.

Description

Safety helmet

A kind of gasbag-type crash helmet relates to the improvement of helmet structure.

For the personage who generally drives motor vehicle or the personage in construction site, it is extremely important to wear the helmet, when taking place, bump can protect the important protector of head to it.The present commercially available helmet, except that firm helmet shell was arranged, inside was provided with suitable vibration damping material, as nylon, sponge etc., but the design of these helmets, all be that the fixed dimension with human body is a design basis, can only the head yardstick when selecting for use cun select for use, can not be general, if excuse helmet size can form loosening phenomenon greater than user's head circumference when wearing, in case impacted, not only do not have protective effect, also may excuse helmet loosening, make the wearer be subjected to continuous collision again from the helmet; What is more, because the vibration damping material in the helmet mostly is chemical fibre, makes the wearer sultry unusual, uncomfortable.

The purpose of this utility model, be to provide a kind of helmet of structure, both can make that producer produces is simply standardized, the model classification is few, reduce die cost, and can relevantly be worn on the wearers head of various head circumferences, both can be ventilated, make that the wearer is unlikely to feel sultry, again because of with people's head circumference appropriateness, do not produce loosening phenomenon, avoided the injury of unnecessary secondary pulse.

The utility model is to implement like this: in the helmet of being made up of cap shell 1 and crash roll 2, between cap shell 1 and crash roll 2, also fit and be equipped with the air bag 3 of a band inflating nozzle 4 and air-vent 5, wherein have the ventilating groove 6 of one or more, with the corresponding charging connector hole, inflating nozzle 4 positions 7 of air bag 3 at the top of cap shell 1.

Below in conjunction with accompanying drawing in detail structure of the present utility model and using method are described in detail.

Fig. 1 is that outward appearance of the present utility model is cutd open and shown schematic diagram;

Fig. 2 is a cut-away view of the present utility model;

Fig. 3 is the design sketch of wearing of the present utility model.

As shown in Figure 1, the utility model is made up of the air bag 3 of cap shell 1, crash roll 2, band inflating nozzle 4 and air-vent 5, wherein have the ventilating groove 6 of one or more at the top of cap shell 1, with the corresponding cap shell 1 in inflating nozzle 4 positions of air bag 3 on also have a charging connector hole 7.

As shown in Figure 1, 2, this gasbag-type crash helmet is taken apart and can be seen, outermost layer is the cap shell 1 that has one or more ventilating groove 6 and charging connector hole 7; The 2nd layer is the air bag 3 that is divided into the hexagon airbag 9 that several air flues communicate with suture 8, and between per 4 close hexagon airbags 9, all sticking into adhesive can not adjacent 4 diamond block 10 that hexagon airbag 9 is ventilated mutually with this, respectively is pressed with an air-vent 5 on these diamond blocks 10; Outermost layer then is a crash roll 2, and this crash roll 2 is to be made by general vibration absorptive material, as nylon, sponge or the like, its shape size is decided according to the cap shell 1 of the helmet, wherein, local accordingly with air-vent 5 positions of air bag 1 on crash roll 2, have air-vent 11 equally.

The utility model is to use like this: after people put on this gasbag-type crash helmet as shown in Figure 3, equally can be because the situation existence of head circumference size and the insufficient applying of helmet size, at this moment, need to give air bag 3 inflations with the air-casing 12 that hand is being pinched on the inflating nozzle 4 that is enclosed within the air bag 2 that exposes cap shell 1, tolerance one in air bag 3 regularly, abut against supporting person's head with being affixed on its outermost crash roll 2, make therebetween space be reduced to cap shell 1 and no longer be loosening shape and be advisable.Under such fit-state, if the common helmet, because the cause of packing, generally give sultry sense of depression, because the utility model has adopted be equipped with a plurality of air-vents 11 on crash roll 2, and these air-vents 11 are to communicate with air-vent 5 on the air bag 3, when the hot gas that sends from the head part upwards from entering the space between air bag 3 and the cap shell 1 after these air-vents 5,11 are uploaded, can flow out with the ventilating groove 6 of space, make that people are unlikely to feel muggy and oppressive to the cap shell.In addition, because inflating nozzle 4 is to adopt the self-locking charging connector in the air bag 3, after people give 3 dozens of intact gas of air bag with air-casing 12, can be sealed voluntarily, easy to operate, can not leak aeration body easily, the safety in having guaranteed to use.

Adopted the said helmet structure of the utility model, can make more fit wearer's head of the helmet, can prevent effectively that the excuse helmet is loosening and make the wearer be subjected to unnecessary secondary pulse.Add the air-vent between each protective layer, the user can be alleviated by wearing the caused feeling of oppression and heat of this sealed protective cap, can extensively be suitable for outdoor study and motorcycle and drive the personage.
